grade A1 kindergarten

june 2012

The Kindergarten Grævlingehuset has received the highest grade A1 for the energy performance certificate. The reason for the high energy performance is, among other things, very few air leakages in the building envelope. The air pressure test measured an air change through leakages of only 0,28 l/s/m2. That is more than 5 times lower the Building Regulations requirement of max. 1,5 l/s/m2.
